## File Input Formats
147+
148+
The `files` input accepts multiple formats:
149+
150+
### Explicit File Paths
151+
Comma-separated list of specific file paths:
152+
```yaml
153+
files: 'lecture/aiyagari.md,lecture/mccall.md,examples/optimization.md'
154+
```
155+
156+
### Glob Patterns
157+
Use shell glob patterns to match multiple files:
158+
```yaml
159+
# All markdown files in lecture directory and subdirectories
160+
files: 'lecture/**/*.md'
161+
162+
# All markdown files in specific directories
163+
files: 'lecture/*.md,examples/*.md'
164+
165+
# Mixed patterns and explicit files
166+
files: 'lecture/**/*.md,specific-file.md'
167+
```
168+
169+
### Supported Glob Patterns
170+
- `*` - matches any characters (excluding path separators)
171+
- `**` - matches any characters including path separators (recursive)
172+
- `?` - matches any single character
173+
- `[abc]` - matches any character in the set
174+
- `[a-z]` - matches any character in the range
175+
146176
## Configuration Examples
